I was hoping you would see this thread, photon. Thanks for the reply
The actual rebuld only takes about 45 mins. It's done after everyone goes home (I'm the last to leave) so it's pretty much sitting idle while it does the rebuild.
It should be simple but I'm not sure the restore would be done in the way you mentioned. I looked at the drive management and it does appear to be a partitioned drive. The O/S partition does not appear to be part of the mirror, only the drive that has all the data.
Permission issues, didn't think of that at all. How does one take ownership of the files?
